摘要： A foam ink composition for printing porous structures comprises stabilizing particles and gas bubbles dispersed in a solvent. The stabilizing particles comprise a predetermined interfacial energy so as to exhibit a contact angle with the solvent of from about 15° to about 90°. At least a portion of the stabilizing particles are positioned at interfacial regions between the solvent and the gas bubbles, thereby stabilizing the gas bubbles in the foam ink composition. A 3D printed hierarchical porous structure comprises one or more continuous filaments arranged in a predetermined pattern on a substrate, the one or more continuous filaments comprising a sintered material and including a porosity of at least about 40 vol.%.

摘要： A soft sensor fiber includes a core conductor surrounded by a dielectric layer, an outer conductor layer and an encapsulation layer. The two conductive layers can be separated by the dielectric layer forming a cylindrical capacitor with resistive electrodes capable sensing strain as function of capacitance, resistance and decay time. The dielectric layer and encapsulation layer can include an elastomer material capable of enduring strains of 250% or more. The core conductor and the outer conductor layer can include a viscoelastic liquid that can include a solvent, an ion source and a thixotropic agent. The soft sensor fiber can be formed by extruding all four layers together to form a four layer fiber having two conductive layers and two insulating or dielectric layers. The soft sensor fiber can be fabricated by a 3D printing process that includes extruding the fiber onto a moving stage.
